If the End User's host is not capable of running an Identity Provider, or the End User wishes to use one running on a different host, they will need to delegate their authentication. For example, if they want to use their website, http://www.example.com/, as their Identifier, but don't have the means, or desire, to run an Identity Provider.

If they have a LiveJournal account (say, user "exampleuser"), and know that LiveJournal provides an OpenID Identity Provider and that it'll assert that they control the Identifier http://exampleuser.livejournal.com/ they would be able to delegate their authentication to LiveJournal's Identity Provider..

- if you open a verisign account
- log into the verisigin account
- create a web page, say "splitbrain.org/openidtest/index.html
- add in the delegation code as I have done inside http://markcross.openid.co.uk/index.html

You will find the when you are logged into the verisign account, when you try to access a wiki with the plug-in installed, you get continually redirected to verisign site saying that you are not logged in.
